IMPROVEMENT IN SKVLIGHTS.

Specification forming part of Letters Patent N o. 143,149, datedSeptember 23, 1873; application led July 14, 1873.

CAsE D.

To all whom it may concern:

Be it known that I, GEORGE HAYES, of the city, county, and State of NewYork, have invented Improvements in Skylights, Conservatories, and otherglazed structures, of which the following is a specification:

The invention, though applicable to other glazed structures, is morespecially adapted to conservatories built mainly of glass and metal. .A

I have the same object in view in this invention as I had in formerpatents granted me, numbered, respectively, 100,143, 106,157, and112,594.; the object being to afford provisionfor expansion andcontraction, so that the parts of the structure will not be undulystrained or broken, and also to facilitate the expeditious erection ofsuch buildings and ail'ord to them lightness and strength, whilelessening their cost.

One part of the invention consists in a novel construction of theroof-bars, wherein angle pieces are employed to aEord `additionalstiffness and strength without increasing the size of the bar so as toobstruct the light unj necessarily. Another part of the invention`consists in a cap-plate of novel construction,

for securing the panes of glass down on the bars.

In the accompanying drawing, Figure 1 is a side view of va bar madeaccording to this invention. Fig. 2 is a transverse section of the same,and Fig. 3 is a like section of a bar having a slightly differentshapedangle piece.

Similar letters of reference indicate correspondin g parts in all theligures.

A is a hollowr triangular bar, which is coml posed of two pieces ofsheet metal, bent each to form one of the sides and half of the top ofthe bar. The bottom edges of these two pieces are bent outward andcurved slightly upward to constitute side glitters g g, and a piece ofmetal, B, is bent over their outer sides to conform to their curvedcontour, and has its edges bent over their edges for the joint purposeof securing itself in place, and thereby uniting the two parts of thebar securely together. The upper edges of these two component parts ofthe hollow bar A are bent upward in juxtaposition to each other, andreceive between them the downward bent edges of the cap-plate C, whichsecures the panes of glass down on the bar. This capplate consistssimply of a piece of sheet metal, bent at the middle for a certain widthinto convex form, and then bent om the outer confines of this portiontoward the middle, whence its edges are bent contiguously in a downwarddirection, to form a tongue, a., which is received between the adjacentbent edges of the bar A. The cap-plate is secured to the bar by means ofrivets c passing through its tongue and the bent-up edges of the bar. Itis made of lead or other soft metal, so that it may be readily bent toadapt it to varying thicknesses in the glass or for other purposes.

The aforesaid convex portions of the capplate constitute two wing-likeparts, which, before the glass is in place, will be bent-up, as shown indotted lines, Fig. 2.

To impart to the hollow bar thus formed stiffness and strength, Iarrange within it a double-angle bar-iron or T- bar, D, having astraight web and laterally-extending arms or ribs at the top. The top orrather the arms of this iron are just wide enough to tit snugly withinthe bar. The bar is thus rendered very strong, and a very eficient meansof securing the glass panes in place is obtained.

For the terminal bar of a building, or for one bounding an opening for ascuttle or the like, the construction of the bar will be slightlymodified, but the same characteristics will be preserved 5 then asingle-angle piece will be used-z'. e., one having but one arm or rib.The bar A in this case will be made of a single piece of sheet metal,which will be bent, as shown in Fig. 3, to form a straight extendedportion, e, and from the ends of this it is bent over double till itintercepts the angle-iron, when the top edge is bent outward along thetop of the bar, and thence downward to the bottom of its web. From thispoint the two parts are bent out laterally together for some distance,and then upward. to form a gutter, g. rlhe edge of the 2. rlhecombination, With the'hollow bar A, lower part is then folded over theother, and of the oep-plete C, substantially as and for the thestructure of the bar is completed; purpose specified.

What I claim as my invention is 1. The combination, with the hollowtriangular bar A, formed as described, of the single or double ribbedangle piece D, essentinlly as and for the purpose herein set forth.

GEORGE HAYES.
